In the current embodiment, the unique information of a wireless transmitter/receiver may include at least one of a Media Access Control (MAC) address, a Service Set IDentifier (SSID), and a Basic Service. Set IDentifier (BSSID). When receiving a signal from the wireless transmitter/receiver, the terminal detects a reception intensity of the received signal. Reception intensity may be in the form of a Received Signal Strength Indication (RSSI).

Thereafter, the information about the wireless transmitter/receiver including the unique information of the wireless transmitter/receiver and reception intensity is transmitted to the service providing apparatus. Also, the terminal may transmit IDentification (ID) information of the terminal to the service providing apparatus, and when receiving the ID of the terminal, the service providing apparatus stores the same. If it is possible to calculate a distance from the terminal to the wireless transmitter/receiver according to signal intensity, the terminal may transmit information indicating the calculated distance.

In step 220, the service providing apparatus determines differentiated services according to information about the wireless transmitter/receiver. The service providing apparatus determines differentiated services according to the unique information of the wireless transmitter/receiver and/or signal intensity included in the information about the wireless transmitter/receiver. The signal intensity is reference information based on which a distance between the wireless transmitter/receiver and the terminal may be calculated. Accordingly, the service providing apparatus provides differentiated services to the terminal according to the distance between the wireless transmitter/receiver and the terminal. Therefore, the terminal may receive, not just a simple service, but differentiated services according the distance between the wireless transmitter/receiver and the terminal. Services may include information such as contents or service Uniform Resource Locators (URLs). Other such information and/or services may be provided in accordance with embodiments of the present invention.
